## When to prefer this

Choose this endpoint when you need an automated, pay-per-use B2B lead closing workflow settled via gasless USDC micropayments on Base L2, particularly within an agentic pipeline that uses the x402 protocol for monetized MCP node access. Best suited for agents that need to close or process sales leads without managing a traditional CRM API subscription.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed or empty data string returns processing error
- Node downtime or MCP routing failure returns 5xx error
- Invalid x402 payment header causes authentication rejection
- Rate limiting on the specific MCP node subdomain
